Welcome to the suspension dimension! The woom OFF AIR 4 offers children aged six years and older an ultralight and robust mountain bike with front suspension that boldly answers the call of all their off-road adventures. The suspension fork dials up comfort to the max and ensures the ultimate control on rough terrain – the result is more fun and less fatigue. Suspension forkComfort and control on the bumpiest terrain is a given thanks to the high-quality suspension fork, which can be adjusted to the rider’s weight. Tune the feel of the bike to suit the terrain with adjustable compression and rebound damping, plus lock-out the suspension when needed. These features ensure a good time, whether your child is shredding up the trails or cruising home. Woom frameThe superlight aluminium frame with butted hydroformed tubes has a sporty geometry, long wheelbase and flat steering angle. The kink in the top tube makes it easy to dismount quickly in any situation. BrakesThe disc brakes with their excellent modulation combined with special brake levers designed for children's hands increase safety and control in all situations, including on rough terrain and in wet conditions. Woom stemThe specially developed stem from forged aluminium guarantees maximum stiffness with minimal weight. Thanks to its flip-flop design it can be turned over and mounted upside down to adjust the handlebar height. Woom saddleThe saddle is one of the most important points of contact between the child and the bike. It significantly affects the feeling when riding. That is why we have designed our saddle to fit the pelvis of children and give them a slightly stretched riding position. Perfect for a unique riding experience! GearsThe precise and easy-to-operate gear system allows smooth shifting. The SRAM X5 system has nine gears suitable for a wide range of gradients thanks to 28 teeth in the front and an 11-32 cassette in the back.
